Description

[Detailed description of the invention] Conventional methods for transferring finished products (rear suspension) onto a trolley (work holder) moved by a conveyor include a method of dropping the finished product onto the moving trolley by aiming. It is not practical because the transfer accuracy becomes very rough, and in the case of heavy objects, shock absorption becomes difficult and damage occurs. If the cart is temporarily stopped, the transfer can be carried out with high precision, but in this case, special conveyor equipment is required, such as using two conveyors and stopping them temporarily when transferring between them, which is expensive, complicated, frequently malfunctions, and increases transfer efficiency. In addition, even if a transfer device that synchronizes along the moving path of the trolley is used, there is a problem with the synchronization accuracy, and since the transfer is carried out during movement, accurate transfer cannot be expected, and it is expensive. It has drawbacks such as frequent failures.

The present invention is an invention to eliminate the drawbacks of the conventional device as described above, and includes a mounting cart equipped with a slideable table on the top and moved by a conveyor;
A front stopper that stops only the table at the transfer position and releases it after transferring the finished product, left and right arms that center the table from left and right, and the table that is activated by a power cylinder before the mounting cart arrives at the transfer position. A table fast-forwarding, temporary-stop positioning device consisting of a fast-forwarding arm that fast-forwards only the table, brings only the same table to the transfer position, and temporarily stops the table, and transfers the product to the temporarily stopped table above the transfer position. It is characterized in that it is equipped with a transfer device to transfer the finished product (rear suspension) onto the top of a mounting cart that is moved by a conveyor. ) is provided with a device that can automatically transfer items with high precision.

According to the present proposal, without slowing down or stopping the conveyor and mounting cart, only the table is rapidly moved to the transfer position by a fast-forwarding arm operated by a power cylinder before the mounting cart arrives at the transfer position. The product is then transferred to the temporarily stopped table by a transfer device, and when the table is released after transferring the product, the mount cart reaches the transfer position under the table and the table is placed on the mount cart. is restored, the product is moved together with the table at the same speed as the mounting cart, and the product can be automatically and accurately transferred to the temporarily stopped table, and the table speed can be increased after the product has been transferred. This eliminates the need for the required distance for product transfer, significantly simplifies the structure, improves product transfer performance, and eliminates restrictions on conveyance speed, making it possible to achieve a desired constant conveyance speed. In addition, the conveyor speed can be easily increased or decreased by changing the table slide length of the mounting cart.
High-speed conveyance is possible, and the speed can match the speed of previous and subsequent work processes. Furthermore, the present invention does not require a complicated conveyor or transfer device, has a simple structure, has few failures, and has practicality such as the ability to directly connect a cart to the conveyor.

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a side view of the proposed device, in which the mounting cart 1 is moved to the right side by the chain conveyor 2 via the metal fitting 2', and the upper portion of the mount cart 1 is slidable in the front and back direction (progressing direction) and also in the left and right directions. It is provided with a table 4 mounted by a sliding mechanism 3 so as to be able to move. In addition, the product can be moved up and down in the longitudinal direction (left and right) and by a chain (or rope) 15', and is held by suction or other means directly above the table that is stopped at the transfer position C'. A transfer device 15 that accurately transfers the
is provided. In FIG. 1, only the front stopper 5 and the fast-forwarding arm 11 of a temporary stop positioning device (described later) are shown for purposes of illustration.

Next, details of the temporary stop positioning device for the table 4 will be explained with reference to FIG. The front stopper 5, which stops the table 4 at the transfer position C', has its base pivotally mounted, and its tip rotated from outside the table 4 travel path to the front side of the table 4 by a hydraulically actuated piston 6 so as to come into contact with the front surface of the table 4. The left and right arms 7 and 9, which center the table 4 from the left and right sides, have their bases pivoted and are rotated by hydraulically actuated pistons 8 and 10, with their tips pointing to the left side of the table 4. , so that it presses against the right side, and both the left and right sides have the same structure.

Furthermore, the arm 11 that fast-forwards the table 4 is
It consists of a dog-shaped arm 11 pivotally attached to the tip of a piston rod 12' of a hydraulic piston, that is, a power cylinder 12, and rotates the operating end side of the arm 11 (the table's travel path side) from outside the table's travel path to the inside. The opposite short piece of the arm 11 is guided by an inclined guide 13' and a horizontal guide 13 so that after the piston rod 12' has moved, the arm 11 is further advanced over a long distance in the path by rapid extension of the piston rod 12'. The extension speed of the piston rod 12', that is, the forward speed of the arm 11, is much higher than that of the conveyor 2, and the table 4 is rapidly moved relative to the mounting carriage 1 due to the speed difference. The front stopper 5 and arms 7, 9, and 11 described above constitute a device that rapidly moves the table 4, temporarily stops it, and positions it.

Next, to explain the operation of this embodiment, when the mounting cart 1 reaches the position A before arriving at the transfer position, it is detected by a limit switch or the like, and in response to the signal, the hydraulic piston 6 is activated and the front stopper 5 is activated. While the short side of the arm 11 comes out of the inclined guide 13', the working end side of the arm 11 is rotated by a hydraulically operated piston 12, ie, a power cylinder, which is located on the front side of the table 4 and operates in response to the above-mentioned signal. 4, then move forward at high speed, push the rear of table 4, slide it on mounting trolley 1, and move to position B'.
C′, that is, advance to the transfer position and stop.
Before the table 4 approaches position C', the left and right arms 7, 9 are rotated to the left and right sides of the table 4 by hydraulically actuated pistons 8, 10, which are activated in response to a series of signals, to center the table 4 (mount (It has no relation to the left-right swing of truck 1.) The solid line positions of the front stopper 5, the left and right arms 7, 9, and the arm 11 in FIG. 2 indicate a state in which the table 4 is at a fixed position, ie, positioned, temporarily stopped and fixed on both the front and rear, left and right sides. At this time, the transfer device 15 is in the position shown in FIG. 1 in synchronization with the above operation, and transfers the product (rear suspension) supported while the table 4 is stopped onto the table 4 with high precision. On the other hand, the table 4 on the mount trolley 1 was originally
It has been slid to the rear limit position,
When the table 4 is fast-forwarded by the arm 11 and reaches the transfer position C', the table 4 is slid to the front limit position of the mount cart 1, and the mount cart 1 is located at the solid line position B relative to the table solid line position C' in FIG. Further, if the transfer is completed while the mount truck 1 moves forward to position C, the transfer can be performed without decelerating or stopping the mount truck. By setting the slide length of the table 4 in accordance with the traveling speed of the mounting cart, sufficient transfer time can be ensured and the transport speed can also be changed. Immediately before the mount cart 1 arrives at position C, the front stopper 5 and left and right arms 7 and 9 are rotated in the opposite direction to release the table 4. At the time of release, the mount cart 1 reaches the transfer position below the table 4. The table is advanced together with the mounting cart. During this time, the arm 11 is moved back and removed from the path of movement of the table 4, and the transfer device 15 also prepares for the next operation, completing the series of operations.

In the description of the above embodiment, since there is no need to use special mechanisms for the table slide mechanism 3, each part of the table fast-forward/pause positioning device, and the operation control mechanism of the transfer device, the specific description thereof will be omitted. It is omitted.

Moreover, the pistons of each part need not be particularly limited to hydraulic operation.
